An ergonomic safety program would address all the following risks EXCEPT:

  • Chemical-related injuries

  • Strains

  • Musculoskeletal injuries

  • Repetitive motion disorders

Correct answer: Chemical-related injuries

An ergonomic safety program would address the following risks: strains, musculoskeletal injuries, and repetitive motion disorders. This field primarily studies the interaction between humans, machinery, and other equipment to determine the best ways to prevent work-related accidents.

Chemical-related injuries would not be addressed in an ergonomic safety program.

What is a technique for planning the most efficient way to achieve a given objective by determining the activities and events required and showing how they relate to each other in time?

  • Critical path method

  • Gantt chart

  • Pareto analysis

  • Short-interval scheduling

Correct answer: Critical path method 

The critical path method (CPM) is a technique for planning the most efficient way to achieve a given objective by determining the interrelated activities and events required and showing how they relate to each other in time. CPM is often used in conjunction with a Gantt chart.

Short-interval scheduling, sometimes referred to as short-interval production schedule (SIPS), is a short-term schedule involving a two- to four-week look ahead. Used often in production environments and increasingly in construction, it requires a greater level of detail in planning and logistics than a typical project management plan.

Pareto analysis is a statistical technique used in problem-solving and decision-making to select a few items or tasks that will produce the greatest overall effect. It uses the Pareto Principle (also known as the 80/20 rule): by doing 20% of the work, companies can generate 80% of the benefit of doing the entire job.

A Gantt chart is a common project management tool that lists activities to be performed on a timeline. The duration of an activity is shown with a line or bar and is a helpful tool for viewing a project at the macro level.

John is the CEO of a medium-sized firm of 150 employees specializing in road construction. In order to get his buy-in, his safety coordinator explained which major reason for measuring health and safety performance?

  • To provide information to those accountable for the performance of the program

  • To provide information to insurance companies

  • To provide information to the public about the company's level of commitment to safety

  • To ensure that employees are held accountable for implementing the program

Correct answer: To provide information to those accountable for the performance of the program

A key purpose of measuring performance is to provide information to decision-makers and those accountable for the safety and health program's overall success. The information measured drives the implementation and development of the health and safety management system. By providing information on how the system operates in practice, risks can be controlled, areas can be identified where remedial action is required, and a platform can be provided for continual improvement, feedback, and motivation.

Health and safety performance is not measured in order to provide information to insurance companies, to provide information to the public about the company's level of commitment to safety, or to ensure that employees are held accountable for implementing the program.

64.

The molecular weight of hydrogen sulfide is 34. Convert 14.1 ppm of hydrogen sulfide to mg/m3.

Use the formula: mg/m3 = (ppm)(MW)/24.45, where ppm = parts per million, mg/m3 = measured mg/m3 of the contaminant, MW = molecular weight of contaminant, and 24.45 = constant = 1 g-mol

  • 19.6 mg/m3

  • 23.2 mg/m3

  • 16.8 mg/m3

  • 29.5 mg/m3

Correct answer: 19.6 mg/m3

To convert from ppm to mg/m3, use the following equation:

mg/m3 = (ppm)(MW)/24.45 

mg/m3 = (ppm)(MW)/24.45 = [(14.1 ppm)(34 g/mol)]/24.45 g/mol

mg/m3 = [(14.1 ppm)(34 g/mol)]/24.45 g/mol = 479.4 ppm/24.45

mg/m3 = 479.4 ppm/24.45 = 19.6 mg/m3

65.

Insufficient motor vehicle safety is one of the leading causes of workplace injuries and fatalities. Seat belts, dual braking systems, and penetration-resistant windshields are regulations that can be attributed to which of the following?

  • Dr. William Haddon and the Energy Release Theory

  • Dan Petersen and the Accident/Incident Theory

  • Heinrich's Domino Theory

  • Smith's Behavior Theory

Correct answer: Dr. William Haddon and the Energy Release Theory

Dr. William Haddon, the creator of the Energy Release Theory, was formerly the head of the National Highway Transportation Safety Administration and was involved in motor vehicle safety. He helped impose new regulations for cars, including mandatory airbags, seat belts for all occupants, penetration-resistant windshields, dual braking systems, and other safety measures. In Energy Release Theory, Dr. Haddon portrays accidents using a model of energy release and transfer and posits that an accident is caused by out-of-control energy.

Petersen's accident/incident theory explains accidents mostly as a result of human error, although system failure may occur as well. According to Heinrich's Domino Theory, a personal injury only occurs as a result of a hazard, which exists only through the fault of careless persons or poorly designed or improperly maintained equipment. 

Behavior theory focuses on employee motivation and reinforcement; it was not developed by Smith.

66.

Employees should not enter a hazardous waste site until what has occurred?

  • They have received adequate training

  • Until 30 days after being hired

  • The site has been cleared of all debris

  • They have been fitted with personal protective equipment

Correct answer: When they have received adequate training

Employees should not enter a hazardous waste site until they have been trained to a level matching their job role/responsibilities and the degree of anticipated hazard.

General site workers should be trained in the site safety plan; safe work practices; nature of anticipated hazards; handling emergencies and self-rescue; rules and regulations for vehicles; safe use of field equipment; handling, storage, and transportation of hazardous materials; employee rights and responsibilities; use, care, and limitations of personal protective clothing and equipment; and safe sampling techniques.

These training thresholds are explained in the Hazardous Waste Operations and Emergency Response (HAZWOPER) section of the 29 CFR 1910.120 regulations. In general, 40 hours of initial training is required with eight hours of annual refresher training thereafter, in addition to site-specific training for each new site.

There is no specific time frame like 30 days to enter a hazardous waste site.

Clearance of debris is not relevant to when a worker can enter a hazardous waste site.

Being fitted with PPE does not ensure that the worker has the knowledge and skills necessary to safely navigate a hazardous waste site.

67.

What is the distinct difference between electrical bonding and electrical grounding?

  • Bonding is connecting conductive objects to each other, while grounding is connecting those objects directly to the earth.

  • Bonding is connecting one conductive object to the earth, while grounding refers to connecting two or more objects to the earth.

  • Bonding aims to reduce static electricity, while grounding aims to reduce the chance of electrical shock.

  • Bonding eliminates the static charge, while grounding equalizes the charge.

Correct answer: Bonding is connecting conductive objects to each other, while grounding is connecting those objects directly to the earth.

Bonding is connecting two or more conductive objects with a conductor, such as a copper wire, to neutralize the potential charge between them. 

Grounding is connecting one or more conductive objects directly to the earth using ground rods or similar. Unlike bonding, grounding drains the static charge away as quickly as it is produced.

The aim of both processes is to control static electricity. Grounding eliminates the charge, while bonding equalizes the potential charge.

68.

All the following are ways to prevent suspension trauma EXCEPT:

  • Use your legs as much as possible

  • Relax as much as possible

  • Lift your knees into a sitting position

  • Swing yourself upside down periodically

Correct answer: Use your legs as much as possible

Suspension trauma, or orthostatic intolerance, is an abnormal response to being in a sustained vertical position and can result in serious injury or death. To minimize the effects of the trauma while suspended with a harness, lift your knees into a sitting position, relax as much as possible, and, if possible, swing yourself upside down periodically. 

There are harnesses with unfolding trauma relief straps and small bars on which workers can stand. These allow the person to feel as though they are standing rather than hanging and can minimize suspension trauma.

69.

A worker is lifting a container with a width of 0.75 meters. Their hands are located 0.5 meters from the floor. What is the horizontal component?

Use the equation H = 20 + (W/2) where H = horizontal component and W = width of the container

  • 57.5 cm

  • 60 cm

  • 52.5 cm

  • 45 cm

Correct answer: 57.5 cm

For a vertical distance of 25 cm (0.25 m) or less, the equation to determine the horizontal component is calculated by H = 20 + (W/2). 

Convert meters to centimeters.

0.75 m x 100 = 75 cm

H = 20 + (75/2)

H = 20 + 37.5 = 57.5 cm

70.

The company you work for is interested in implementing a new training program. You are asked to determine the Return on Investment (ROI) of this program to your company. Which of the following could you use to find the ROI?

  • Cost-benefit analysis

  • Training suitability analysis

  • Context analysis

  • Work analysis

Correct answer: Cost-benefit analysis

Cost-benefit analyses are conducted to determine the ROI to the company from the original investment in training costs.  

Training suitability analysis thoroughly reviews how an activity is performed with the goal of assessing whether training is the desired solution to an identified issue. Context analysis is undertaken to evaluate what training is needed. Work analysis targets the skills and performance requirements necessary for the job.

71.

Per OSHA, to develop a site emergency action plan, what should be the FIRST item covered?

  • An evacuation procedure, including routes and assignments

  • A chain of command, including incident commander duties

  • A list of employees who are trained and current in CPR/first aid

  • The location of the nearest in-network medical provider

Correct answer: An evacuation procedure, including routes and assignments

Emergency action plans and their requirements are discussed in OSHA's 29 CFR Part 1926.35. This section and its coverage of emergency action plans apply to OSHA standards that require them.

The first item in the plan is an evacuation procedure, including escape routes and assignments. The other elements are also part of a plan but not listed first by OSHA.

72.

What is the sample variance for the following dataset?

Location# of Incidents
NJ5
DE7
NY12
CT12

  • 12.67

  • 38

  • .9

  • 18.67

Correct answer: 12.67

Variance is a measure of the variability of a sample from which the standard deviation is derived. Most scientific calculators will provide a variance as part of a statistical calculation of a data sample.

The equation for sample variance (s2) is s2 = [Σ(X-mean)2]/n-1.

First, calculate the mean.

mean = (5+7+12+12)/4 = 9

Then find (X-mean) and (X-mean)2 for the data points:

Location# of Incidents(X-mean)(X-mean)2
NJ5-416
DE7-24
NY1239
CT1239

Insert into the formula:

s2 = [Σ(X-mean)2]/n-1 = (16 + 4 + 9 + 9)/(4-1)

s2 = (38)/3

s2 = 12.67

The standard deviation, σ, would be equal to the square root of the sample variance or σ = (12.67)1/2 = 3.56

73.

A truck transporting a compressed gas would require which class of placards?

  • Class 2

  • Class 3

  • Class 1

  • Class 8

Correct answer: Class 2

Class 2 is for compressed gases, regardless of other properties. The US Department of Transportation (DOT) requires transporters to display placards when moving hazardous materials to alert emergency response personnel to the contents.

Class 3 is for flammable liquids. Class 1 is for explosives. Class 8 is for corrosives.

74.

Regarding the NIOSH Lifting Equation, how is lifting frequency defined?

  • Number of lifts in a 15-minute period

  • Number of lifts in a 60-minute period

  • Number of lifts in an 8-hour period

  • Number of lifts per job

Correct answer: Average number of lifts in a 15-minute period

The NIOSH Lifting Equation was designed to calculate safe lifting guidance for two-handed manual lifting tasks. The multi-variable equation requires understanding the geometry of the workstation and how often the lift is performed within a 15-minute period.

Lifting frequency (F) is the average number of lifts per minute over a 15-minute period.

75.

What is the mode of the following set of data?

3, 6, 7, 7, 8, 10, 12, 13, 14

  • 7

  • 8

  • 9

  • 11

Correct answer: 7

The mode is the variable that appears most often in a set of data. 

The mean, or average, of the set is 9 (rounded up from 8.9). The range, or difference between the highest and lowest values in the set, is 11. The median is the middle value in a list of data. There are nine values in this set in numerical order, and 8 is the central point (median).

76.

What is a document that lists items involved in an accident, how each item can fail, the effects of the failure, means of detection, and actions?

  • Failure Modes and Effects Analysis

  • Fault tree analysis

  • Multi-linear Event Sequencing Method

  • Gross Hazard Analysis

Correct answer: Failure modes and effects analysis

A Failure Modes and Effects Analysis (FMEA) is a step-by-step approach that seeks to identify where failures occurred. It can be demonstrated in the form of a table, listing all items used in the task involved in the accident. The investigation will identify and list the way (or mode) in which each item can fail, assess the effects of each failure, evaluate methods of detection, and prescribe actions and recommendations.

A fault tree analysis uses a logic diagram to model the pathways within a system that can lead to a foreseeable, undesirable loss event. The Multi-linear Event Sequencing (MES) method uses a timeline to display the sequence of events that contributed to or were the direct cause of the accident. A Gross Hazard Analysis (GHA) is performed to get a rough assessment of the risks involved in performing a task.

77.

What should a company track to assess the competency of the work force and the effectiveness of their safety training? 

  • The willingness to report near misses

  • The training budget

  • The number of training sessions

  • The number of posted job hazard analysis

Correct answer: Reported near misses

When people report near misses, it shows how actively they are engaged in safety. The more an individual reports near misses, the better they are at identifying hazards. This provides a good indication of the competency of the workforce and the effectiveness of safety training. 

78.

Asbestosis is scarring of the lungs due to asbestos inhalation. The condition's severity depends on all the following factors EXCEPT:

  • The age of the exposed person

  • How long the person was exposed to asbestos

  • At what concentrations the person was exposed

  • Whether the exposed person is also a smoker

Correct answer: The age of the exposed person

Asbestosis is a respiratory disease caused by the inhalation of asbestos fibers. When inhaled, the fibers reach the inner lung and create scarring of the lung tissue. The severity of the disease depends entirely on how long the person was exposed to asbestos and at what concentrations. 

Smoking, in addition to asbestos exposure, has been strongly correlated with lung cancer. Research has not shown a relationship between the severity of asbestosis and the age of the exposed worker.

79.

Which chemicals react vigorously with moisture, resulting in extreme heat, and can be potentially flammable, corrosive, toxic, or reactive?

  • Water-reactive or water-sensitive chemicals

  • Halides

  • Acidic metals

  • Oxidizing chemicals

Correct answer: Water-reactive or water-sensitive chemicals

Water-reactive or water-sensitive chemicals react vigorously with moisture. The reaction can result in extreme heat and can be potentially flammable, corrosive, toxic, or reactive.

Some examples of water-reactive chemicals are calcium carbide and alkali metals (e.g., sodium, lithium, potassium). Water-reactive chemicals are identified as physical hazards in the OSHA Hazardous Communication standard (1910.1200). Water reactivity would also make a waste "characteristic" under RCRA if it was not already a listed waste.

80.

What is the purpose of water armor or a "turtle suit"?

  • To protect the body from high-pressure blasts

  • To prevent heat-related injuries

  • To protect the body from cold-related injuries

  • To prevent falls

Correct answer: To protect the body from high-pressure blasts

One of the better examples of protective clothing against high-pressure water blasting (also known as water jetting or hydroblasting) is the TurtleSkin water armor suit. This suit is designed to protect the chest, legs, and arms against up to 40,000 psi without sacrificing worker mobility.

The suit is not meant to protect workers against cold- or heat-related injuries or falls.

A turtle suit does not prevent falls.
